Multifunctional mixing system helps extend commercial success at Harpoon Brewery

High-quality beer choices available to enthusiastic consumers

DATE 2023-11-28

Harpoon Brewery is an American craft brewery with roots in a driven passion for beer, along with a determination to make more high-quality beer choices available to the enthusiastic
consumer. Harpoon was started in 1986 on the Boston waterfront – the first brewery to commercially brew and bottle beer in Boston in more than a quarter of a century.

Harpoon puts a lot of energy into developing a wide range of tastes and styles, including limited-batch specialty beers, seasonal brews and innovative beers. One notable example is Imperial Pumpkin, a decidedly unconventional stout brewed with pumpkin, nutmeg and cinnamon. 

The Harpoon Brewery engineers decided to install the Alfa Laval Iso-Mix system, based on the revolutionary Alfa Laval Rotary Jet Mixer technology, in all the new bright beer tanks.

The Iso-Mix system enables Harpoon Brewery to introduce the required amounts of both water and CO2 very quickly and with accurately set specifications, thereby ensuring beer
of consistently high quality. The same technique is used for adding the spices and natural fruit flavours so important in many Harpoon products.
